' CHARLES J EANNIN, OF WATERIBURY, CONNECTICUT.

WINDOW-BLIND ADJUSTER AND HOLDER.

To all who'm it may concern:

Be it known that I, CHARLES JEANNIN, a citizen of the Republic ofSwitzerland, residing at Waterbury, in the county of New Haven and Stateof Connecticut, have invented new and useful Improvements inWindow-Blind Adjusters and Holders, of

which the following is a specification.

The present invention relates to an improved window blind adjuster andholder, designed particularly for use in connection with the windowblinds of residences or dwellings,'or other places where such a deviceis applicable.

The primary object of the invention is the provision of a device used inconnection with each of a pair of windowblinds, and operable from theinterior of the house, to swing the blinds to adjusted or desiredposition, and to hold the blinds when so adjusted so that theymay not beswung by the wind, and the blinds are prevented from rattling or makingundesirable noises, be-

cause of the fact that they are retained in a rigid immovable position.

The invention consists in certain novel combinations and arrangements ofparts as will be hereinafter more fully described and claimed.

In the accompanying drawings I have illustrated one complete example ofthe physical embodiment of my invention constructed according to the.best mode I have so far devised for. the practical application of theprinciples of the invention;

Figure l is an outside elevation view of a window and its blinds,showing one of the blinds closed, and another one partly open. Fig. 2 isa horizontal sectional view of Fig. 1, showing both blinds closed. Fig.3 is an enlarged view in sideelevation, showing the operating parts ofmy blind opener, some parts being shown in section. Fig. 4 is asectional view of Fig. 3 at line 44. Fig. 5 is a face view of theoperatlng handle or knob. Fig. 6 is a face view of the adjustment plate.Fig. 7 is a view in side elevation showing the actuating device of theinvention with the elements thereof separated.

For the purpose of illustrating the application of my invention, I haveshown an exemplification ofa window frame 1, equipped with the upper andlower window sashes 2 and 3, respectively, while the two blinds 44 arehinged at 55, to swing outwardly from the window, and a pair of leafSpecification of Letters Patent.

device, and these are indicated as incased within the housings 7 and SinFig. 1, where the housings are'shown secured to the win- I dow sill 9.similar construction and, therefore, a description of one will sufficefor both. Each window blind is equipped with a bevel gear wheel 10 whosestem 11 is fixed in a retain- The operating devices are of i ing strap12 that is secured rigidly and firmly to the blind near its lower end.Each of the bevel gear wheels 10 is'provided with a stud or pin 13projecting into the body of the strap 12 so that the bevel wheel 10 willturn with the swinging movement of the window blind. It will be notedthat the two hinge joints 55 of the blind and the axis of the stem 11are invertical alinement, so that the bevel gear wheel 10 will revolveor rotate as the window blind swings on its hinges. To

permit the stud or pin 13 to swing about its axis, the housings 7 V and8 are provided with circular slots 14.

To accomplish the swinging motion of the window blind, I employ anactuating device which extends from the outside of the window sill 9inwardly to the interior of the room with which the blinds to the windowsashes are used. These actuating devices comprise a sectional. rod,preferably cylin: drical in cross section, and made up of the portions15, 16 and 17. The joint between the portion 15 and its reducedextension 17 7 forms afshoulder 15, and the two portions 15 and 16 arecut away at 18 and 19 in order to form' flat faces complementary to eachother, and adapted for frictional contact with each other. By thisconstruction whereby the ends of the two bar sections 15, 16 overlapeach other, it will readily be seen that the length of the operating barmay be varied within limits to suit the width of the wall of the housein which the device is used, and yet preserve the function of the barand permit its rotation. At the end of the bar section 16, a bevel gearwheel 20 is fixed which meshes with the bevel gear wheel 10, and at theother end of the operating bar a knob 21 is located. This knob has abase 22,

and isperforated at 23 so that the opening 24 in the reduced extension17 of the operating bar, alines with the opening 23, and the handle orknob is fixed to the extension 17, which'enters 'a socket 23, by meansof a pin 25 passing through the openings 28 and 24:. In this manner thewheel 20, when the handle or knob 21 is turned,will rotate the bevelwheel 10. The head 22 of the knob 21 is provided'with a singlepinor'stud 26, and 7 this stud is adapted to co-act with the circularplate 27 to adjust the position of the window blind. The platej27isfperforated to accommodate the extension bar 17, and

the plate is secured by means .of the lugs 28 and screws 29, to theinner face of the'wall just below the Window sill. "Upon the face of theadjustment plate or disk 27, are arranged in circular form a series ofsockets 30, any one of which is adapted to receive the pin 26 of thehandle 21, so that the operating bar may be turned by utilizing thehandle or knob 21, and the pin 26 may be seated a selected socket 30. g

The "operating bar is preferably incased within a cylindrical sleeve orbarrel 31, and thisbar is provided with a head 33 counter bored to forma cupf34=. Thehead is preferably provided with prongs or pointed studs35 toengage the material inwhich the sleeve 7 is embedded and holdsv thesleeve against displacement. Within the sleeve, confined between theshoulder 15 and the adjustment plate 27, is a spring 36 which surroundsthe reduced extension bar 17, and holds the handle 21 in plaoewith'thepin 26 in its socket 30. A second spring 38 is located between thereariof the bevel gear wheel-20 and the "face, 39'of the counter borehead 33,-and it will. be seen that this spring holds the head 20 in meshwith the head. 10. V

The operation of the device will be evident from an inspection of thedrawings. When it desired to swing the blind on its hinges, the knob orhandle 21 is first pulled to the left in Fig. 3, to withdraw the pin'26from the socket 30. This action. moves the bar section relation tothesection 16, the

distance the handle 21 is pulled from the adjustment plate 27, and theflat faces of the cut away portions 18, 19, glide over each other, butremain in frictional contact. The entire bar may now be turned to theright or left, as required, and this action revolves the bevel gearwheel 20, and through it the wheel 10 is rotated to swing the blind onits hinges as described. lVhen the blind has been swung to the desiredposition,-the handle 21 is released and the pin 26 is permitted to enterone of the sockets 30 to lock the handle with relation to the adjustmentof the plate, the spring 36 returning the section bar 1517, and handle21 to proper position, and then holding the pin 26 in its socket 30.When in this position it will be evident that the blind cannot be swungin either direction, for it is locked by the engagement of the pin 26 inits socket 30.

From the above description taken in connection with my drawings it isevident that I have provided an efficient device for performing thefunctions required of the blind bar within said sleeve having a bevelgear in the head engaging said teeth, a spring between the head and gearcoiled about the end of the bar, an adjustment plate secured to the endof the sleeve opposite the bevel gear, a circular series of slots on theplate, and saidsectional bar having a reduced portion supported in theplate, a spring between said. plate and a shoulder on thebar and coiledabout the reduced portion, a knob fixed at the end of the reducedportion, and a locking pin on the knob adapted to engage one of saidseries of sockets.

In testimony whereof I afiix my signature.
